3 Claim 1- 11:7dl5.

This invention relates to a'foldable article of furniture.

A Object of th p se t ention i the ision of a fo'ldable article offurniture which on e n u ed ll ide prote tion fr m'drai Q unshine nd wilc re P iva y 1 A ic a ob e t is t e r vision of f din bed suitable foruse in institutions, field hospitals and the like, which as it is beingunfolded will raise a s d an cure ii fi ien p iv cy to theoccupantofthebed.

Other objects. ofthe. present invention will be oome apparent inthecourse of the specification.

In accomplishing the objects .of the present'in. vention it was foundadvisable to provide a frame adapted to receive abed which is pivotedthereto through two arms, .anda vertical shield slidable in said framewhich 'islorought into operating position automatically'by .the'moving.of thebed from its folded position into its unfolded position.

The invention will appear more clearly from the following detaileddescription when taken in connection with the accompanying, drawin s,showing. y y of example. pr ferred embodiments of the inventive idea.

Inthe drawings:

Figure 1 is a perspectiaeviewnf abedembodying the present invention, inunfolded position, with the screen up.

Figure 2 is an endview, partially in section, of

the bed in folded position, with the screen down.

Figure 3 is an end view of a pair of beds in unfolded position, showingthe pivoted legs bearing on the ground.

Figure 4 is a front view of a bed in folded position, showing analternative construction of feet having hinged casters capable of beingswung into non-operating position.

Figure 5 is a horizontal section along the line I 5-5 of Figure 1.

Figure 6 is a horizontal section along the line 6-6 of Figure 1.

Figure '7 is an enlargement of one of the casters shown in Figure 4showing the caster in nonoperating position.

In a bed shown in Figures 1, 2, '3 and 4, an upright rectangular,substantially fiat frame structure 8 comprising rectangular componentframes 25, 26, joined by spanners 21, 28, is supported by beams 9, Ill,with its length parallel to the ground. The parts are preferably ofangle iron, as illustrated. The beams 9, Ill, terminate in feetcomprising knobs l3, l4, l5, and lips 35 extending upward from a pointimmediately inward of the knobs on the beams, the lips-35 having holes34 formedtherein. Rectangular platform H is pivoted toicoinponent frameby straight flat links 18, I9 andr vots 2. 0 2 2, n is e y f ldia lintoi h rameg s n Fi re 2 and 4, and nfoldable therefrom as in Figures 1and 3. Legs l1, I8 are pivoted to the outer corners of plato m .l andbear att i er e d ns 334 A. ch nne 2. x ends betw en th ed componentframes 25, 26, and in this channel the shield 23 is Vertically slidable.Pins 29, 3!] in shield23 engage the inner side member 3! of platfiorml.l. It willbe noted that innerside member 3| is lower when the bed isfolded than when it is 5 unfolded due to pivots l 2 and 2| being locatedintermediate inner side member 3] and outerside member'32, The bed thushas a low outline when folded as well as having the unfolded platform atreguia bedte t M -In"operation,' starting with the platform and shieldin folded: position as shown in Figure 4, pressure exerted downwardlyand outwardly on outer side member, 32 ofplatf orm I I causes platformI] to. unfold and'to raise shield 23by the upward'motion of inner sidemember- 3! transmitted through pins 29 and 3B. The lower ends ofpivotedlegs'll, I Bfare then rested on beams 9,

*llL inwardly'of thelgnobs l4, l5 as shown in Fi re andi'l c ed iini e ten b e P 1 gaging the holes'34 in the lips 35, and the assembly can beslid from place to place on knobs l3, l4, l5, etc. Alternatively thepivoted le s l1, l8 can be rested on the ground perpendicularly as inFigure 3. If it is desired to use the bed without raising the shield,starting with the platform folded as in Figure 4 the lower side member3| of platform I l is moved outwardly, disengaging pins 29, 30 and thebed unfolded as above.

Figure 3 shows a duplex bed, similar in all respects to the bed ofFigures 1 and 2 except that a second platform 38 similar to platform His pivoted to component frame 26.

Figure 4 shows an alternative construction comprising casters 39, 40,fastened to beams 9, I0,

are absent, as in emergency hospital facilities, or in use as an extrabed in the home.

The shield rises automatically as the bed is unfolded, and can stay downin itschannels if so desired.

Ease of movement of the assembly, with provision for solid bearing onthe ground where movement is not desired.

Sanitary construction. Bed, vermin do not breed in movable joints andthere are no unfilled holes or crevices.

Easy cleaning of the under surface of the bed when in folded position.

Mattress ventilation in semi-folded position of the bed.

Adaptability for use as a shelter or oxygen tent by placing a blanket,sheet, or shelter half over the bed and raised shield.

It is apparent that the illustrations shown above have been given solelybyway of illustration and not by way of limitation, and that the abovedescribed articles are subject to wide variation and modification. Allofsuch variations and modifications are to be included within the scopeof the present invention.

What is claimed is: 1. A foldable article of furniture, comprising twoupright frames, beams extending transversely to the lowerends of saidframes and supporting swingable into one of said frames into a foldingposition and out of that frame into anunfolded position; and meanstransmitting the swinging motion of saidplatform to saidjshield toreciprocate the latter.

.2. A foldable article of furniture, comprising an uprightframestructure having a vertical channel formed therein, at least two beamsextending transversely to thelower end of said frame strucfoldedposition, means transmitting the swinging motion of said platform tosaid shield to reciprocate the lattenieach of said beams comprising afoot portionhaving a ground-engaging knob and a substantially upwardlyextending lip; and legs pivoted to said platform, each of said legsbeing swingable in the unfolded position of said platform from aposition of engagement with the ground to a locking position inengagement with a separate lip.

3. A foldable article of furniture, comprising an upright framestructure having a vertical channel formed therein, at least two beamsextending transversely to the lower end of said frame structure andsupporting said frame structure, a shield vertically reciprocable insaid channel and extending'substantially above said frame structure inthe unfolded position of the article of furniture, a rectangularplatform, straight flat links connected to said platform intermediateits ends and pivotally suspending said platform from said frame tomaintain the inner side of said "platform adjacent the lower end of saidshield,

said platform being swingable into said frame into a folding positionandout of the frame into an unfolded position, means transmitting theswinging motion of said platform to said shield to reciprocate thelatter, each of said beams comprising an end portion, a plurality ofcasters, means swingably I attaching a separate caster to each endportion to enable the caster to swing from an operative ground-engagingposition to a raised inoperative position, and a separate fixedsupporting member carried by each end portion and. extending above theground when said casters are in their operative positions;
